In Fig. 14 we increase the time period to 100 days and plot the infected cell popula tion and viral load under mixture of all four controls U1 , U2 , U3 , U4. With all four controls with each other we see that the infected cell count and also the viral load is less compared to the various combinations discussed above for the entire time period thought of.

This proves that combined drug therapy can be powerful in keeping the viral load low.7 Comparative Effectiveness StudyIn this section we carry out the comparative effectiveness study for the systemdS = dt- SV – S,(7.1)dI = SV – d1 + d2 + d3 + d4 + d5 + d6 I – I, dt(7.two)16 Web page 22 ofB.

Drugs that inhibit viral replication: Each and every in the four interventions Arbidol, Remdesivir, Interferon, Lopinavir/Ritonavir does this job. So we now choose to be (1 – 1 )(1 – two )(1 – 3 )(1 – four ), where, 1 , 2 , three , 4 are chosen depending on the efficacy of the drugs Arbidol, Remdesivir, Interferon and Lopinavir/Ritonavir, respectively. two. Drugs that block virus binding to susceptible cells : Arbidol does this job. So we now choose to be (1 – ), exactly where would be the efficacy from the drug Arbidol in blocking virus binding to susceptible cells.R0 plays a crucial role in understanding the spread of infection inside the person, and V determines the infectivity of the virus in an individual. Taking the two sorts of interventions into consideration, we now possess a modified standard reproductive quantity RE in addition to a modified virus count V E with the endemic equilibrium as follows:Optimal Drug Regimen and Combined Drug Therapy and Its Efficacy…Web page 23 of 28RE = VE = -(1 – 1 )(1 – two )(1 – three )(1 – 4 ) (1 – ) , (b1 + b2 + b3 + b4 + b5 + b6 + 1 )(d1 + d2 + d3 + d4 + d5 + d6 +.
